Abstract
The paper states as increasing influence of forestry and biogenic factors on the degradation of oak forests and the necessity of creating of geographical crops of common oak from climatypes native to different regions of European Russia in the silvicultural areas of the Tellerman experimental forestry unit of the Institute of Forest Science of the Russian Academy of Sciences. The morphometric features and preservation of oak crops over time were studied in 14 geographical climatypes. The best indicators for survival, growth energy and resistance to biogenic factors for edaphic conditions and, possibly, for the entire region of the southern forest-steppe zone were found in seeds belonging to climatypes from Smolensk, Tula, Belgorod, Orel, Kursk 1, Kursk 2, Tatarstan and Adygea. High-quality forest restoration using acorns of local origin collected in high-standing mountain oak groves is possible only under the condition of removing the pressure of ungulates.
